SPECIFICATION forming part of Letters Patent No. 293,976, dated February19, 1884.

Application filed May 19, 1883. (No model.) I

1'0 aZZ whom it may concern: Beit knownthat I, ROBERT H. D.MoRRIsoN, acitizen of the United States, residing at WVinona, in the county ofWinona and State of Minnesota, have invented certain new and usefulImprovements in Pipe-Returns; and I do declare the following to be afull, clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to lettersor figures of reference marked there on, which form a part of thisspecification.

Figure l of the drawings is a representation of this invention, andshows a side view of the two parts joined. Fig. 2 is a view of the innerface of one piece. Fig. 3 is aview of the under side, showing the twoparts together.

This invention has relation to improvements in the manufacture ofsteam-pipe elbows; and it consists in the construction and novelarrangement of parts, as will be hereinafter more fully set forth, andparticularly pointed out in the claim appended.

Heretofore elbows have been constructed in sections, with each sectionprovided at adj acent ends with perforated flanges for the reception ofconnecting-bolts, but such elbows have not been provided with theflanges hereinafter specified.

The object of my invention is to provide a strong and durable elbowwhich may be manufactured at a very small expense. This object Iaccomplish by the means shown and illustrated in the accompanyingdrawings, in which the respective sections are indicated by the lettersband 0, which are provided with flanges d d. These flanges extendtransversely around. the outer sides of the adjacent ends of eachsection, and communicate at the under side of c the sections withweb-flanges g, which, when the sections are placed together, extendsolidly from one branch to the other.

i indicates flanges around the mouth of each section,which alsocommunicate with the web- 4 5 flanges. These flanges are all cast ormade integral with relation to each section, and when the sections areconnected by passing bolts through the perforated lugs Z of the flangesd d an elbow is formed, of the construction shown in Fig. l of thedrawings, with all the flanges meeting solidly at the adjacent faces ofthe sections.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

The pipe elbow consisting of the sections 1) and 0, cast with archedperforations, and flanges d (2 around the mouths of said sections,forming the adjacent faces of the sections, and perforated lugs for thefastening-bolts, and with base-flangesz', extending to the adjacentface-flanges and joining the same in angular form, the angles beingsolidly filled by the metal of the sections, all substantially asspecifled.

In testimony whereof I aflix my signature in presence of two witnesses.

ROBERT H. D. MORRISON.
